Description
Cardnit 6.4mg Tablets contain Glyceryl Trinitrate (Nitroglycerin), a nitrate used for the prevention and treatment of angina pectoris (chest pain) caused by coronary artery disease.
It works by relaxing and widening blood vessels, allowing more blood and oxygen to reach the heart, thus reducing chest pain and improving exercise tolerance.
Cardnit is an effective anti-anginal medicine that helps manage episodes of chest discomfort and prevent future angina attacks when taken regularly as prescribed.
